Mango meal with peel was evaluated as carbohydrate source in substitution of corn, for tilapia juvenile growth and carcass composition. There were used 180 fish (4,69 ± 0,06 g) in 12 tanks of 500 L, fed three times a day (6 % of live weight), in a water recirculating system with biofilter. Four diets were evaluated with different mango meal concentrations T1= diet with 30 % of corn; and T2, T3 and T4 in which 33, 66, and 100 % of corn was replaced by mango meal. All of the treatments had three repetitions. At the end of 45 days performance was evaluated (final weight, weight gain; specific growth rate, feed consumption, apparent feed conversion rate, carcass yield, survival) and chemical carcass composition. The levels of mango meal substitution by corn meal affected all the variables analyzed from level 33 % (p 0,05). Carcass chemical composition values were changed except for ash. Mango meal in substitution for corn may be used until the level of 33 % in Nile tilapia feed without damage for growth performance and carcass chemical composition.
